I'm surprised to hear you say that. I've tested with gcc-4.9.4, 6.4.0,
7.1.0; and clang-4.0, and none of them warn about {}
I think when we went through this before (in NIR) we couldn't use {}
because it needs to compile with MSVC, and MSVC doesn't allow that in
C.

I don't really understand the nuances of {0}, {0,}, {{0}}, etc, and I
get the sense that that's the case for nearly everyone else as well.
The most prominent bug I see in all of this is that {} isn't part of
standard C (it is part of standard C++!)
